Answer:
second option
Step-by-step explanation:
Answer:
6a^8/3a^4= (6/3)= 2
a^8/a^4= a^4
2a^4
(6/3)(a^8/a^4)= 2a^4
(6/3)(a^(8-4))= 2a^4
Step-by-step explanation:
Answer:
23.44%
Step-by-step explanation:
The probability of getting a 4 on the first 2 throws and different numbers on the last 5 throws = 1/6 * 1/6 * (5/6)^5
= 0.01116
There are 7C2 ways of the 2 4's being in different positions
= 7*6 / 2 = 21 ways.
So the required probability = 0.01116 * 21
= 0.2344 or 23.44%.
It's been such a long time, but I think (1) should be the addition property since your adding 5 to both sides.
And (2) should be the multiplication property due to multiplying both sides by 2.
Reduce each ratio to its minimum expression to find if they are equal.
35:28

10:8

Since both ratios reduce to 5:4, they are equivalent.
Another way to check a:b is equivalent to c:d, is that a*d = b*c
In this case, this will be true if 35 times 8 is equal to 10 times 28:

Since both products are equal, then the ratios are equivalent.
